The satellite doesn't help very much. It doesn't help at all if you want to send a transaction or Mike your own blocks. It's also very easy to know whether it's broadcasting. So if the mechanism by which Bitcoin is banned is legal, it's easy to find the owner and prosecute them for breaking the law. I'm not incredibly familiar with ham, but if you ever broadcast then you're inviting the authorities to find you, and shut you down. If you strictly communicate point-to-point it doesn't seem likely that you'd be able to tell the entire world about new blocks within a reasonable about of time. If you keep the 10 minute block interval then delays longer than, say, 1 minute, would be extremely problematic. I'm not sure how a Ham radio network could reliably tell the world about new blocks within 60 seconds without alerting the authorities.
